NOVELTY - Antibacterial polyolefin comprises 100 pts. wt. polyolefin resin, 0.2-1 pts. wt. composite antibacterial agent and 0.1-1 pts. wt. antioxidant, where the composite antibacterial agent is graphene oxide having surface-loaded nano-silver particles. USE - Used as antibacterial polyolefin. ADVANTAGE - The antibacterial polyolefin: exhibits remarkable antibacterial properties and wide antibacterial range; is safe, low harm to the human body, environmentally friendly and low pollution degree; and has no odor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing antimicrobial polyolefin, comprising mixing polyolefin resin, composite antibacterial agent and antioxidant into a high-mixer and mixing for 5-15 minutes, then adding mixed material into a twin-screw extruder, kneading and extruding to obtain antibacterial polyolefin, where the extrusion temperature in each extrusion section of the twin-screw extruder is 140-165 degrees C, 175-185 degrees C, 180-190 degrees C, 180-195 degrees C, 180-195 degrees C, 180-195 degrees C and 185-200 degrees C respectively.
